## Summary description

VIEGA reducer tee 22x15x22 mm (MPN 100445) is a plumbing fitting that joins three pipes with a reduced middle branch. Designed for creating branch connections between 22 mm and 15 mm pipe runs, it provides a reliable mechanical transition in water and heating systems. Suitable for use with compatible VIEGA pipe systems and standard plumbing installations.

## Long description

VIEGA reducer tee 22x15x22 mm is a three-way plumbing fitting designed to create a mechanical branch between two parallel 22 mm runs and a reduced 15 mm branch. Manufactured by VIEGA, this reducer tee provides a compact transition point for potable water and heating circuits where pipe diameters change. It is intended for use with compatible VIEGA pipe systems and common installation methods in residential and light commercial plumbing.
Advantages
The reducer tee delivers a secure mechanical connection with a clear stepped reduction from 22 mm to 15 mm, ensuring flow continuity and minimizing turbulence at the junction. Its compact form saves space in manifolds and tight routing areas, while the standardized dimensions simplify integration with existing 22 mm and 15 mm piping. The fitting is suitable for repeated professional installation practices and supports reliable performance in water and heating systems when used with appropriate joining techniques and compatible VIEGA components.
Suitable for
 Branching potable water supply lines between 22 mm and 15 mm pipes
 Creating tees in domestic heating circuits where a reduced outlet is required
 Compact installations and manifold connections with limited space
 Repairs or modifications to existing 22 mm pipe runs that require a smaller branch
Key specifications
 Material and connection type: designed for mechanical joining with compatible VIEGA system pipes
 Pipe diameters: two 22 mm inlets/outlets and one reduced 15 mm branch
 Application media: potable water and central heating fluids where compatible with system materials
 Installation environment: indoor plumbing and heating installations, service cabinets and manifolds
 Form factor: compact tee with a stepped reduction for space-efficient routing
How to use
Select the reducer tee when you need to divert flow from a 22 mm run to a 15 mm branch while maintaining two 22 mm continuations. Prepare pipe ends according to the VIEGA system instructions and local plumbing standards, ensuring cut ends are square, deburred and clean. Assemble the fitting using the appropriate joining method specified for the VIEGA product family you are using (mechanical press, push-fit, or compatible connector type). Verify alignment and support the piping to prevent stress at the joint, then pressure-test the system after installation to confirm watertight integrity.
Usage recommendations
Use only with compatible VIEGA pipes and connectors and follow the manufacturer’s installation instructions and local plumbing codes. Avoid exposing the fitting to aggressive chemicals or temperatures beyond the limits of the connected pipe system. Support the reduced branch to prevent strain and perform a pressure test after installation to confirm correct assembly.
